SPECIFICATION forming part of Letters Patent No. 670,887, dated March 26, 1901.

Application filed .Iuly 7, 1900. Serial No. 22,798. iNo model.)

T (t/7, whmn, zizi 'may concern:

Beit known that I, LEROY S. PFoUTs, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Incandescent Vapor-Burners; and

- I do hereby declare that the following is a full,

clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, and to the numerals of reference marked thereon, in which the figure is a longitudinal section of uthe burner-head and mixing-tube.

The present invention has relation to incandescent vapor-burners; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.

In the accompanying drawing, 1 represents the body of the generator, which is substantially of the form shown, and, as shown, it is provided with the hollow rib 2, within which hollow rib is located the removable tube 3, said removable tube benggfor the purpose of holding a wick fiber or gran nlated. substance through which the fuel passes.

For the purpose of holding the removable tube 3, together with its contents,in proper position the screw-threaded plug 4 is provided, which screw-threaded plugcloses the bottom or lower end of the hollow rib 2 and at the same time provides a proper support for said tube. From the top or upper end of the hollow rib 2 extends the passage 5, which passage leads to and communicates with the chamber 6, and from the chamber 6 leads the down-passage 7, said down-passage extending to and communicating with the gas-tip 8.

For the purpose of regulating the su ppl y of fuel the ordinary needle 9 is provided. Directly over the gas-tip 8 is located the airmixing tube lO, which air-mixing tube is provided with the air-inlets 11, it being understood that any desired number of inlets, such as 11, may be provided; but only one is illustrated in the figure.

The top end of the body 1 is provided with the head 12, which head is provided with the gauze disk 14. The head 12 is provided with the flange 16, which liange is for the purpose of holding in proper position the ring 17. The mantle is located between the inner peripheryof the ring 17 and the outer periphery of the shell or casing of the chamber 13. For the purpose of producing better generation and at the same time allowing the bottom or lower portion of the mantle to become properly incandesced the ring 17 is provided with the spaced projections-or teeth 18, which projections or teeth are extended upward and around the outer periphery of the mantle, so that a greater amount of heating-surface is provided Without cutting off the supply of air to the mantle, by which arrangement the mantle becomes incandesced between the bottom of the projections and their tops.

In the drawing I have illustrated the teeth spaced a short distance from each other; but it will beunderstood thatit is immaterial as to the exact location as to the teeth, except that they are to be located around the mantle and upon the outside thereof.

For the purpose of feeding air to the bottom or lower end of the mantle the head 12 is provided with the passages 19, which air-passages are located as shown in the drawing, one passage being illustrated; but it will be understood that any desired number of passages, such as 19, may be provided without departing from the nature of my invention.

It will be understood that an ordinary feedpipe, such as 20, is to be provided and said feed-pipe at some point provided with a cutoff valve, such as 21.

Having fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a burner comprising a body having a hollow rib and generatingpassages formed in such body and rib, such passages terminating in a vapor-discharge jet-tip', a mixing-tube located over such tip, a head mounted on such body and at the upper end of the mixing-tube such head being provided with a flanged collar, a ring supportedon said collar and provided with spaced projections so arranged that a space is formed between the head and such projections, into which the lower end of the mantle is received, substantially as and for the purpose specified.

2. The combination of a burner comprising a body having a hollow rib and generatingpassages formed in such body and rib, such passages terminating in a vapor-discharge IDO jet-tip, a mixing-tube located over such tip, a head mounted on such body and at the upper end of the mixing-tube such head being provided With a flanged collar having air-passages, a ring supported on such collar and provided with spaced projections so arranged that'a space is provided between the head and such projections, into which the lower end of the mantle is received, substantially as and for the purpose specified.

3. The combination of a burner comprising a bodyhaving a hollow rib and generatingpassages, a removable tube located in one of the passages formed in such body, such passages terminating in a vapor-discharge jettip, a mixing-tube located over such tip, a
